libata-sff: kill dummy BMDMA ops from sata_qstor and pata_octeon_cf
Now that SFF and BMDMA are completely separate, sata_qstor and pata_octeon_cf which inherit from ata_sff_port_ops don't need to worry about BMDMA ops being called. Kill the dummy BMDMA ops. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
